Does anyone have any suggestions on how to interpret "normal", "steeper", "flattening", "flat or even inverted"?

Full Recession - the yield curve is normal.
(Is yield curve reaching top?)
Early Recovery - the yield curve is beginning to get steeper.
(Is yield curve dropping?)
Late Recovery - In this stage, interest rates can be rising rapidly, with a flattening yield curve.
(Is yield curve getting bottom?)
Early Recession - interest rates are at their highest; and the yield curve is flat or even inverted.
(Is yield curve rising?)
